JAMES ALLEN, OF ALLISTON, ONTARIO, CANADA.

FIFTH-WHEEL FOR VEHICLES.

SPECIFICATION formingpart of Letters Patent-No. 273,427, dated March 6, 1883.

Application filed December 9, 1882.

To all whom it may concern:

Be it known that I, JAMES ALLEN, a subject of the Queen of Great Britain, residing at the village of Alliston, in the county of Sincoe, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvernen ts in Vehicles, of which the following is a specification.

The object of the invention is to provide a strong and effective fifth-Wheel arranged to operate without the king-bolt, and in which its working parts will always be lubricated.

Figure l is a perspective view of the fifthwheel, showing its connection with the bedplate and axle. Fig. 2 is a longitudinal section through my.

A is the lower half of the fifth-wheel, having a groove, a, cut round its top surface to receive a projection, 1 formed on the upper half, B, of the fifth-wheel.

O is a metal bed-plate, made solid with the lower half, A, of the fifth-wheel. On either side of the bed-plate O, cast therewith and extending from the lower halt, A, of the filthwheel, are formed the lugs d, which lugs form a lateral connection with the head-block D and axle E. 3

F is a socket cast on the center of the metal bed-plate C, which socketis designed to receive a projection, G, cast on the center of the headplate H, which bed-plate is made solid with the upper half, B, of the fifth-wheel.

I is a metal reach-plate, made solid with the head-plate I1 and upper half, 13, of the fifthwheel.

0 are lugs cast on the upper half, 13, of the fifth-whee], on either side of the head-plate, for the purpose of forming a lateral connection with the head-plate of the vehicle.

J is a stay-rod, one end of which is bolted to the reach-plate I and its other end to a lug, f, cast on the upper half, B, of the fifth-wheel,

(No model.)

on the opposite side to that from which the reach-plate I extends, but on a line passing through the center of the wheel and the center of the reach-plate.

g are nuts screwed on either end of the stayrod J, two nuts being provided for each end, one nut placed .below the lug and reach-plate,

- and the other above them, in order to permit the easy adjustment ofthe said stay-rod. This stay-rod, it will be noticed, passes round theaxle-plate, which has a boss or projection, h, cast on its bottom, through which boss a bolt, 2', projects, passing through the stay-rod and forming a pivotal point upon which the said stay-rod revolves.

From the foregoing description it will be seen that there is no necessity for a king-bolt, the socket F and projection G acting as such. It will also be seen that the bearing-points of the fifth-wheel are easily lubricated. Oil or grease being placed in the groove to and in the socket will always lubricate these parts.

I am aware that a fifth-wheel without a kingbolt is not new; also that several parts of the upper and lower sections of a fifth-wheel have been formed integrally therewith, and make no claim to such construction, but limit my invention to the peculiar construction, arrangement, and combination of parts described, and pointed out by the claim.

What I claim as my invention is- The combination, in a fifth-wheel for vehicles, of the reach-iron I and lug f, formed in one piece with the upper part, B, brace J, adjusting-nuts g, bolt '1}, projection h, head-block D, axle E, bed-plate 0, socket F, projection G, and head-plate H, all constructed and arranged substantially as shown and described.

JAMES ALLEN.
